Geochronological studies on the crystalline bedrock from NE Poland – an overview and summary.
A b s t r a c t. Since the mid-1950s, when Jerzy Znosko started his huge contribution to the recognition of the crystalline basement of NE Poland, many different studies have followed the planned and implemented drilling projects. The drillings, conducted in the first decade under the leadership of Professor Znosko and under his description of the results, were further worked out by other researchers. Studies concerned petrological, geochemical and mineralogical aspects. In that fan of methods applied, geochronological data started to be introduced to the bibliography of the area in the early 1960s. Geochronological methods that time mean mostly K-Ar and some Rb-Sr values. These materials are gathered in the paper aiming at its presentation, re-valuation and interpretation in terms of the significance of such data for further development of knowledge.
